Do you need sunscreen in winter? Yes! Many people believe that no sun = no sunscreen. The logic sounds convincing. There’s less sunlight, colder temperatures, and fewer outdoor hours. Unfortunately, it is a common misconception.
In this guide, we dive into common winter sunscreen myths, data on UV risks in winter, dermatologist inputs on the use of sunscreen, and practical tips for UV protection.
Why Sunscreen Matters Year-Round
Sunlight contains UV (ultraviolet) rays, including UVA and UVB, which affect your skin health. Thus, SPF is an everyday essential.
UV rays explained (UVA vs UVB) –
-
UVA rays: Highly penetrable, surpassing clouds and glass to reach cells deeper in your skin. They are present year-round and can cause premature aging. They’re also associated with the risk of skin cancer.
-
UVB rays: Damage the outermost layers of the skin. Overexposure can give you a burning sensation, resulting in sunburn. They vary seasonally, becoming more intense in summer and less in winter.
In short, UVA = “aging rays” and UVB = “burning rays.”
Cumulative skin damage and aging –
Sun damage accumulates quietly over the years. In the long term, daily exposure accumulates and leads to photoaging, characterized by wrinkles, sun spots, and loss of skin elasticity.
Here’s what scientific studies have to say:
-
People receive most of their sun exposure before the age of 21. In fact, 20-25% of total UV exposure by age 60 happens during childhood. Children also receive 3 times more UV rays each year than adults. Thus, protecting them from UV exposure is important for reducing their risk of developing skin cancer later in life.
-
Tanning often attracts teenagers and young adults, leading to years of high UV exposure. Starting artificial tanning before age 35 raises the risk of melanoma, the deadliest skin cancer, by 75%.

Common Myths About Winter Sunscreen
Below are three popular sunscreen-related myths in winter debunked:
“The sun is weaker in winter”
The intensity of UVB rays may decrease during winter, but UVA rays stay strong year-round. In fact, reflective surfaces, like snow and ice, increase exposure to UV rays. Dermatologists share that “Winter UV is still potent enough to cause damage.”
“Clouds block UV rays”
Is it important to apply sunscreen on cloudy days in winter? Yes.
Many people skip SPF on cloudy days, believing that UV rays cannot penetrate clouds. However, the Skin Cancer Foundation reports that up to 80% of UV rays pass through clouds. So, the risks remain.
“Cold weather means no sunburn”
Lower temperatures do not mean less UV intensity. The UV radiation and its effect stay the same. However, cool skin may delay your awareness of burning, increasing your exposure and associated risk.
The Science: Winter UV Risks Backed by Data
Snow reflection and UV intensity
Albedo effect refers to a surface’s ability to reflect sunlight. And how much does snow reflect UV rays? 80 to 90% of UV radiation on average because it has a high albedo.
Consequently, shoveling snow or skiing doubles your exposure, direct and reflected rays from the snow. Research on dermatoses (skin diseases) in snow skiers found whole-face tanning in skiers due to high UV exposure.
High altitude + skiing/snow boarding UV risks
Higher altitudes have thinner atmospheres and thus stronger UV rays. UV intensity increases by 4% for every 1000 ft of elevation. That’s why individuals in winter sports, like skiing and snowboarding, experience higher exposure even in cold weather.
Here’s a comparison table to put things into perspective:
|
Elevation Levels |
UV index (compared to sea level) |

Depends on surface characteristics, like:
|
|
5,000 ft |
20-30% more |
|
10,000 ft |
Almost 50% more |
Dermatologist quotes + studies
A board-certified dermatologist and University of Texas professor said, “Risk of sunburn can also increase when engaging in popular winter activities where one is exposed to higher altitudes and additional UV light reflects from surfaces, such as snow for skiers and snowboarders”.
Medline Plus notes that reflected UV rays from snow can harm your eyes and raise the risk of eye melanoma (skin cancer).
Practical Winter Sunscreen Guidelines
When to apply sunscreen in winter (everyday vs outdoor sports)
-
Indoor days: Since UVA rays penetrate windows, SPF on face and hands is still needed.
-
Outdoor activities: Apply a dermatologically recommended sunscreen for winter with SPF 30+. Reapply every two hours for better protection during skiing, snowboarding, hiking, and other activities.
-
How to apply: Apply at least 1 teaspoon of sunscreen 15 minutes before stepping out. Cover all exposed areas like the neck and ears. Our Fluid Brightening Sunscreen with SPF 50+ works well for dry skin. Similarly, the Gel Sunscreen with SPF 55+ is formulated for oily skin. They protect and hydrate your skin while preventing sun damage.
-
Layering: Use your sunscreen after a moisturizer to avoid dryness.
SPF levels & formulations for winter
-
SPF Level: A dermatologist-recommended sunscreen for winter is broad-spectrum, cream-based, and hydrating with SPF 30 or above.
-
Formulation: Opt for mineral sunscreens with zinc or titanium. They are effective in reflecting UV rays.
-
All-round care: Apply a lip balm with SPF for added protection.
Quick check: Should you apply SPF today?
-
Are you going outside for more than 20 minutes?
-
Is there snow on the ground?
-
Are you at a high altitude or going skiing?
-
Is it cloudy but daylight?
If the answer to any of these questions is yes, apply SPF.
Conclusion: Why Sunscreen Is Essential Even in Winter
There are too many myths about sunscreen in winter that stop people from protecting their skin when the temperature drops.
The UVA rays always stay, even on cloudy, winter days. You may not feel very warm due to the cold weather. However, you are constantly exposed to the risks of UV damage, like sunburns, aging, tanning, and skin cancer. So, do you need sunscreen in winter? Yes, every day.
